LEVER-LOCKING MECHANISM.

Application filed September 2'2, 1917.

To all whom it may concern:

Be it known that I, GEORGE C. JENSEN, a citizen of the United States,residing at Oakland, in the county of Alameda andstate of California,have invented certain new and useful Improvements in Lever-LockingMechanism, of which the following is a specification.

The present invention relates to a locking device for levers,particularly that type employed in connection with lever engaging yokes,which are in turn associated with. the variable gear shifting mechanismof motor driven vehicle.

The invention has for its principal objects to provide a constructionpreferably associated with the lever through a pivotal connection andadapted to be thrown into engagement with a. stop by the operation oflock controlled mechanism to prevent operative movement of the lever.

With the above mentioned and other objects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings and ointed out inthe claims hereto appended; it being understood that various changes inthe form, proportion, size and minor deta ls of construc tion within thescope of the claims may be resorted to without departing from the spiritor sacrificing any of the advantages of the invention.

To more fuliy comprehend the invention, reference is directed to theaccompanying drawings, Wherciu--- Figure l is a view in verticai sectionthrough the preferred embodiment of my invention.

Fig. 2 is a broken. top plan view of the same. 7

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Referring more particularly to the several views of the drawings,wherein like characters of reference designate corresponding parts,1indicates a suitable hollow casing in the top wall. 2 of which isprovided a pair of parallel spaced guide slots 3 connected by thetransverse selective opening 4. Extending transversely Within thehousing is a suit- Speeification of Letters Patent.

able rotatable shaft 5 on which is pivotally mounted a lever 6 extendingupwardly through the selective passage 4 in the top wall 2 of thehousing 1. The lever 6 is capable of transverse movement through theopening 4 and of longitudinal movement Within the openings 3.The'springs (5' positioned one at each side of the lever normollymaintain the same in an upright po sition within the selective openingat.

Extending upwardly within the housing and positioned one at each side ofthe lever 13 are the lever engaging forks 7 and 8, one of whrh issecured to rotate with the shaft 5 an the other of which is mounted torotate about the shaft 5 and carries the sleeve 1 The upper ends of thelever engagii'ig forks 7 and 8 are adapted to lie one at each side ofthe opening 4 and to be engaged hy the lever in its selective movement,said forks being connected in any suitable manner to the gear shiftingelements of the variable speed power transmitting mecha- 111511livotally connected, as at 10, to each of the forks 7 and 8, adjacenttheir upper ends, are the locking arms ll and 12, each provhlcd in itsupper surface with a notch 13 in which is adapted to be received a stop14 depending from the underside of the housing top wall 2. The lockingarms are adapted to move longitudinally during the pivotal movement ofthe lever engaging forks asso ciated therewith .and the free ends ofsaid arms slide on and are supported by a suitable rotatably mountedshaft 15 extending transversely of the same. The shaft is provided withan operating handle 16 disposed exteriorly of the housing 1 and beneaththe point of contact with the respective locking arms is provided withdepressions 17 which are adapted when the shaft is rotated to positionthe same to receive the free ends of the locking arms to permit thelocking arms to dro and iie free of the stops 14, at which time t elever engaging forks are free for pivotal n'lovenient.

Springs 18 hooked over the upper surface of the locking arms and coi edabout the shaft 15 and secured at one end thereto, maintain the locklngarms in contact with rotate the bolt on the remeans to position thedethe free ends of the said bolt, and also lease of its lockingpressions 1T beneath locking arms 12.

Any suitable mechanism may be employed for locking the bolt 15 fromrotation, and for purposes of illustration I employ a bolt locking pin19 rotatably mounted in a bore 20, and intersecting the axis of rotat onof said bolt 15. To permit of the rotation of the bolt 15 the boltlocking pin 19 is formed with a semi-circular depression 21 adapted onthe rotation of said pin 19 to receive the solid portion of said bolt15. The bolt 15 is likewise formed with a suitable semi-circulardepression 22 which receives the solid ortion of the bolt locking pin 19when said bolt 15 is locked from movement.

A spring 23 is coiled about the bolt looking pin 19 and is connected atone end thereto, said spring acting to rotate the bolt locking pin toforce the solid portion thereof into the recess 22 of the bolt 15. Atongue 24 extends upwardly from the upper end of the bolt locking pin 19and is adapted to be engaged by a cooperating tongue 25 depending fromthe underside of a rotatable key controlled locking barrel 26, of anywell known type.

The rotation of the locking barrel 26 a one-quarter turn in a clockwisedirection will cause the solid portion of the bolt looking pin 19 towithdraw from the semi-circular depression 22 in the bolt 15, and thesemi-circular depression 21 in the bolt locking pin 19 to register withsaid depression 22, at which time the tension of the springs 18 willrotate the bolt 15 a one-quarter revolution and present the depression17 below the respective locking arms 12, permitting free operation ofthe lever engaging yokes 7.

On a one-quarter revolution of the bolt 15 in an opposite direction bythe manual movement of the handle 16, the depressions.

17 are removed from immediately beneath the locking arms 12, and thearms are forced upwardly by riding on the surface of the bolt, causingthe stops 14 to seat in notches 13, at which time the spring 23 willautomatically rotate the bolt locking pin 19 a one quarter revolutionand cause the solid portion thereof to be received in the recess 22, atwhich time the lever engaging yokes are locked from movement.

Having thus described my invention, what I claim as new and desire toprotect by Letters Patent is In combination with a housing, a leverpivotally mounted therein, a locking arm within said housing, pivotalmeans interposed between said arm and said lever for forming a uniontherebetween for operative connection of the lever and arm, said armcapable of longitudinal movement on the operative movement of saidlever, a stop for said arm, and an axially rotatable lock controlledmeans for supporting and guiding said arm in its longitudinal movementand capable of operation for forcingsaid arm into engagement with saidstop.
